Take your M135i from quick to devastatingly capable with KW’s Clubsport triple-adjustable damper kit. This motorsport-bred upgrade gives you precise control over rebound, low-speed compression and high-speed compression, letting you fine tune balance, traction and ride to suit circuit work, B-road blasts and daily use. If you want razor-sharp response, huge grip and confidence at the limit on a rear wheel drive BMW hatchback with EDC, this is the package.
